3. Turn the thermostat knob G to setting 4.
turning movement of the knob A should be made as follows:
In gas OFF position the knob is pressed and turned clockwise to the
12 volt position, If 110 volt operation is desired press once more and
continue the clockwise turning to the 110 volt position marked "ELEC".
LEVELING
In the boiler of the cooling unit, ammonia vapor is distilled from an ammonia-water
mixture and carried to the finned condenser where it liquefies. The liquid f
the evaporator inside the cabinet where it creates cold by evaporating into a
circulating flow of hydrogen gas. If the evaporator is not level the liquid readily
accumulates forming pockets vhich can impair the gas circulation or block it com-

When the vehicle is stationary it must be leveled to be comfortable to live in. If

number . A higher setting of the temperature control will be required in summer
than in winter.
The setting of the temperature control determines the action of the thermostat
in relation to freezing compartment temperatures,
